Re: [Samba] samba-ad restart fails occasionally




Hai MJ,

You know there is 4.6.3 for wheezy available?

Found here: http://apt.van-belle.nl/ 
The wheezy repo contains only samba packages ( and samba related ) 

echo "deb http://apt.van-belle.nl/debian wheezy main contrib non-free" >> /etc/apt/sources.list.d/van-belle.list 
wget -O - http://apt.van-belle.nl/louis-van-belle.gpg-key.asc | apt-key add -


What you can do is get the source and get the init from the 4.6.3. if you want to stay on the 4.5 sernet line. 

Can you post the files :

/etc/logrotate.d/samba
/etc/init.d/smbd
/etc/init.d/samba
/etc/init.d/samba-ad(-dc)
/etc/init.d/nmbd 

But then the sernet versions. 
I'll have a look. 

But i do suggest, upgrade to the 4.6.3 packages or .. Its time... To upgrade to jessie, and get the 4.5.8 packages ( or the 4.6.3 ) 


Greetz, 

Louis
